Triggering geolocation fix acquisitions on transitions between physical states

摘要

A method and device for triggering acquisition of geolocation fix information. The method include determining activity state information based on information from one or more sensors. It is determined if an activity state has transitioned to a particular activity state based on the activity state information. Geolocation fix information is acquired if the activity state transitioned to the particular activity state.

1. A method for triggering acquisition of geolocation fix information comprising:
obtaining sensor information from at least one sensor; determining, using the sensor information, activity state information based on:
determining normalization information on the sensor information;extracting a sliding window based on the normalization information; andcomputing features from time-domain information and frequency-domain information based on a magnitude of a frequency response obtained based on the sliding window; determining whether an activity state has transitioned between particular activity states based on the activity state information; and triggering geolocation fix information based on a determination that activity state transitions between the particular activity states.
